The variability of arterial blood pressure (BP) is considered an important cardiovascular risk factor.
To verify the possible associations between the postprandial and the sleeping blood pressure variability.
This study evaluated systolic, diastolic, mean, pulse pressures and heart variability in 69 elderly patients in preprandial, postprandial and sleeping periods. One 24 hours ambulatory blood pressure monitoring was used for measurements and the results were showed in the time-rate index.
We observed a decrease in the systolic blood pressure values from preprandial to postprandial and to the sleeping periods (124.7 ± 14.6, 113.2 ± 15.3 and 108.5 ± 13.9mmHg, respectively; p = 0.003). Associations between BP variability of the postprandial and sleeping periods were obtained for systolic, diastolic and mean arterial pressure.
The correlation between postprandial and sleeping BP variability has rarely been demonstrated in the literature. These correlations between BP changes after eating and during sleep might suggest that both events could coexist in other clinical situations.
动脉血压（BP）的变异性被认为是一个重要的心血管危险因素。
验证餐后血压变异性与睡眠血压变异性之间可能存在的关联。
本研究评估了69例老年患者在餐前、餐后和睡眠期间的收缩压、舒张压、平均压、脉压及心率变异性。采用24小时动态血压监测进行测量，并以时间率指数展示结果。
我们观察到收缩压值从餐前到餐后再到睡眠期间逐渐降低（分别为124.7±14.6、113.2±15.3和108.5±13.9mmHg；p = 0.003）。餐后和睡眠期间的血压变异性在收缩压、舒张压和平均动脉压方面存在关联。
餐后和睡眠血压变异性之间的相关性在文献中鲜有报道。进食后和睡眠期间血压变化之间的这些相关性可能表明这两种情况可能在其他临床情形中共存。
